LED Lights Are A ‘Transformative Technology’ In The Developing World

When the news broke Tuesday that three scientists whose discoveries made practical household LED lighting possible had won the Nobel Prize in physics, most Americans probably thought of the LED screen in their TV, or perhaps about whether they might finally consider shifting to energy-efficient LED lighting in their homes. (The LED, or light-emitting diode, makes use of treated or coated semiconductors to produce light. Blue LED lighting — the Nobelists’ invention — was the missing ingredient that allowed the creation of LED lamps.)
